Bitcoin consumes a massive amount of energy. An interesting fact is that at the moment Bitcoin network uses more energy than 159 countries in the world. The Green Protocol is the new innovative mechanism designed from the Bitcoin Green Team. The Green Protocol is fast, secure, energy efficient and is an excellent replacement of Bitcoins algorithm - SHA- 256. Fixed block rewards, proof-of-stake, and masternode are creating better mining experience and coin distribution for the Bitcoin Green holders. A crucial feature of Bitcoin Green is the decentralized governance protocol. The holders of Bitcoin Green can decide how to use the 5% reward from the mined block. They can give it to developers, charity or to help the Bitcoin Green mission.
